Denise Richards and Richie Sambora -- Love Thy Neighbor

Denise Richards and Richie Sambora's secret love affair has sent shockwaves through Hollywood, but these pictures show just HOW close this pair really were to one another.

It turns out that Richards, 35, and Sambora, 46, actually live next door to one another in an exclusive gated compound in Westlake, Los Angeles.

The pair -- who are getting divorced from Heather Locklear and Charlie Sheen, respectively -- were first busted when they were photographed smooching together at Le Cafe restaurant in Westlake Village only 24 hours after Richards filed a blistering 17-page deposition demanding a restraining order against her estranged husband, Sheen.

The pair's walking-distance commute was particularly convenient once Locklear became friendly with Richards and Sheen after Locklear appeared on 'Spin City' with Sheen. Locklear attended the baby shower for their daughter, Lola, and held her after she was born.

No word yet on just what Sheen and Locklear make of this neighborly affair.
